PHP Nested Array convert into flat array - php

Question

I have a problem to transform my hierarchical array like this:
array(
[0]=>
array(3) {
["id"]=>
int(2353011010)
["name"]=>
string(17) "LEDER ACCESSOIRES"
["order"]=>
int(15)
}
[1]=>
array(3) {
["id"]=>
int(2371475010)
["name"]=>
string(15) "SPORT AUFKLEBER"
["order"]=>
int(25)
}
[2]=>
array(4) {
["id"]=>
int(2563635010)
["name"]=>
string(17) "KENNZEICHENHALTER"
["order"]=>
int(10)
["children"]=>
array(6) {
[0]=>
array(4) {
["id"]=>
int(3854259010)
["name"]=>
string(9) "EDELSTAHL"
["order"]=>
int(92)
["children"]=>
array(2) {
[0]=>
array(3) {
["id"]=>
int(20878056010)
["name"]=>
string(5) "test1"
["order"]=>
int(1)
}
}
}
[1]=>
array(3) {
["id"]=>
int(3854260010)
["name"]=>
string(5) "CHROM"
["order"]=>
int(91)
}
}
[3]=>
array(4) {
["id"]=>
int(19754330010)
["name"]=>
string(30) "SCHALTMANSCHETTEN CARBON OPTIK"
["order"]=>
int(3)
}
}
)
Into a flat ones like this:
array(
[0]=>
array(3) {
["id"]=>
int(2353011010)
["name"]=>
string(17) "LEDER ACCESSOIRES"
["order"]=>
int(15)
}
[1]=>
array(3) {
["id"]=>
int(2371475010)
["name"]=>
string(15) "SPORT AUFKLEBER"
["order"]=>
int(25)
}
[2]=>
array(3) {
["id"]=>
int(2563635010)
["name"]=>
string(17) "KENNZEICHENHALTER"
["order"]=>
int(10)
}
[3]=>
array(4) {
["id"]=>
int(3854259010)
["name"]=>
string(9) "EDELSTAHL"
["order"]=>
int(92),
["parentId"]=> 2563635010
}
[4]=>
array(4) {
["id"]=>
int(20878056010)
["name"]=>
string(5) "test1"
["order"]=>
int(1),
["parentId"]=> 2563635010
}
[5]=>
array(4) {
["id"]=>
int(3854260010)
["name"]=>
string(5) "CHROM"
["order"]=>
int(91),
["parentId"]=> 2563635010
}
[6]=>
array(4) {
["id"]=>
int(19754330010)
["name"]=>
string(30) "SCHALTMANSCHETTEN CARBON OPTIK"
["order"]=>
int(3)
}
)
The children antities should be removed and every child element should get a parentId entity of the higher level id. I need this solution for transfering into DB.
thx

Answer 1

Now, I have create a "temporary" method that works for me, but is noch flexible to use:
function recursive($categories) {
foreach ($categories as $value) {
$result[$value->id]['id'] = $value->id;
$result[$value->id]['name'] = $value->name;
$result[$value->id]['order'] = $value->order;
$result[$value->id]['parentId'] = 0;
if(isset($value->children)) {
$parentId = $value->id;
foreach($value->children as $value2) {
$result[$value2->id]['id'] = $value2->id;
$result[$value2->id]['name'] = $value2->name;
$result[$value2->id]['parentId'] = $parentId;
if(isset($value2->children)) {
$parentId = $value2->id;
foreach($value2->children as $value3) {
$result[$value3->id]['id'] = $value3->id;
$result[$value3->id]['name'] = $value3->name;
$result[$value3->id]['parentId'] = $parentId;
}
}
}
}
}
return $result;
}
Do anybody know a recursive solution for this method?
